    kbuild: terminate Kconfig when $(CC) or $(LD) is missing · 902a6898
    Masahiro Yamada authored
    If the compiler specified by $(CC) is not present, the Kconfig stage
    sprinkles 'not found' messages, then succeeds.
    
      $ make CROSS_COMPILE=foo defconfig
      /bin/sh: 1: foogcc: not found
      /bin/sh: 1: foogcc: not found
      *** Default configuration is based on 'x86_64_defconfig'
      ./scripts/gcc-version.sh: 17: ./scripts/gcc-version.sh: foogcc: not found
      ./scripts/gcc-version.sh: 18: ./scripts/gcc-version.sh: foogcc: not found
      ./scripts/gcc-version.sh: 19: ./scripts/gcc-version.sh: foogcc: not found

      #
      # configuration written to .config

    Terminate parsing files immediately if $(CC) or $(LD) is not found.
    "make *config" will fail more nicely.
